Transplant in Chronic Myeloid Leukemia
To the Editor: Autologous transplantation with stem cells mobilized after intensive chemotherapy may achieve Ph-negative hemopoiesis in patients with chronic myeloid leukemia (CML), and this may prolong survival [1]. However, this procedure is not without risks. We report on a case of and seizures. Cerebrospinal fluid study was negative. MRI showed many lesions in both cerebral hemispheres (Fig. 1). On day 50, a maculopapular disseminated Aspergillus flavus infection during the protracted period of neutropenia following mobilization. rash with a few subcutaneous nodules was noted. Skin biopsy revealed a septal panniculitis, and its culture grew Aspergillus flavus. In spite of adding A 34-year-old male was diagnosed in December 1991 with Ph-positive chronic-phase CML. The patient received hydroxiurea throughout his dis-flucitosine, the neurological condition of the patient deteriorated and he died on day 66. Postmortem examination was not allowed. ease, except for a 7-month trial with interferon without any response. After an unsuccessful search for an HLA-identical donor, the patient was proposed ASCT is an alternative therapy for patients with CML who lack an HLAidentical donor [2]. PSC collected during early recovery from intensive for ASCT 40 months from his diagnosis.
With the aim of mobilizing Ph-negative peripheral stem cells (PSC), the chemotherapy may be Ph-and even PCR-negative. Using this material, Carella et al. [1,3] have shown that some patients might achieve a sustained patient received cytarabine, 300 mg/m 2 /days 1-5, mitoxantrone 12 mg/m 2 / days 1-3, and etoposide 150 mg/m 2 /days 1-3. G-CSF (8.8 g/kg/day) Ph-negative hemopoiesis after ASCT. However, this potential benefit must be carefully weighed against the risk of treatment-associated mortality. The was given from absolute neutrophil count (ANC) Ͻ1.5 ϫ 10 9 /l, and the leukaphereses were planned when the absolute white blood cell count Italian Group [1] observed an 8% mortality after transplant in patients who failed to engraft, but there are no clear data about mobilizations's related exceeded 1 ϫ 10 9 /l. Ciprofloxacin and fluconazole were used as prophilaxis against infection. The time of ANC Ͻ0.5 ϫ 10 9 /l lasted 30 days (days mortality. With a similar approach, Kantarjian et al.
[4] reported a 7% mortality for mobilization chemotherapy. 8-38), and the nadir was 0 during 16 days.
On day 21, the patient developed fever and dry cough. Physical examina-Our patient had a 30-day period of profound neutropenia, during which he developed a fatal disseminated aspergillosis by A. flavus. This filamentous tion showed erythema in the catheter exit site, and left lung sibilants. CXR was normal. Streptococcus mitis grew from blood cultures. He was started fungus is ubiquitous, and caution is necessary in the evaluation of its isolation. However, its identification in skin culture (based on morphological on imipenem and vancomycin, and subsequent blood cultures were negative but symptoms persisted. On day 26, bronchoalveolar lavage (BAL) dis-criteria: conidiophores of biseriate) along with clinical evolution is highly suggestive of this diagnosis. [5]. closed fungal elements in the gram-stain. Although cultures were negative, amphotericin B (1 mg/kg/day) was added. In the following days, despite
In conclusion, our case illustrates a risk of life-threatening fungal infection associated with these innovative therapies. This emphasizes the need granulocyte recovery, he developed an interstitial pneumonitis that precluded the leukoapheresis procedure.
